GONCRETE RAILWA'Y-TIE.

Specification of Ietters Patent.

Patented May 30, 1911.

Application filed February 28, 1911. Serial No. 611,415.

To all whom it may concern:

Be it known that 1, JOHN E. Bossrno- HAM a citizen of the United States, residing at Cantori, in the county of Stark and State of Ohio, have invented a new and useful Concrete Railway-Tie, of which the followin' is a specification.

My invention relates to improvements in railway ties and especially to such ties as are made of reinforced concrete.

The objects of my invention are to generally improve devices of the character menrespects.

tioned and to provide a concrete railway tie of simple construction, easily and cheaply made, strong, durable, convenient and practical in use and thoroughly eiiicient in all These objects, together with other objects readily apparent to those skilled in the art, I attain by the 'construc tion illustrated in the accompanying drawings, although my invention may be embodied in other forms, the construction illustrated being chosen by way of example.

In the drawings Figure 1 is a side view of a concrete railway tie embodying my invention and showing the rails properly con nected thereto, a portion of the tie being broken away to decrease the size of the figare, and a portion of the tie being shown in vertical longitudinal section to more fully disclose the internal construction. Fig. 2 is a top or plan view of a portion of the tie showing the rail attached. Fig. 3 is a vertical transverse section of the tie with the rail attached, said view being taken on the line 3-3 of Fig. 1. Fig. 1 is a perspective view on an enlarged scale of one or" the cushion blocks. Fig. 5 is a perspective view from the under-side of one of the supporting anchor blocks. Fig, 6 is a perspective view from the under-side of one of the rail holding caps. I

Throughout the several views similar reference numerals indicate similar parts.

The numeral 1 indicates an inverted steel channel with the side flanges thereof depending, said channel constituting the main reinforcing body and preferably extending nearly to the ends of the tie. On the top of the upturned base of the channel are arart.

ranged the supporting anchor blocks 2 at points above which it is desired to locate the rails 3. Each anchor block is firmly, fixedly connected to the channel 1 by suitable means. such as the rivetset which extend through the apertures 5 in the block 2 and through the base of the channel 1. In two opposite edges of each block 2 are arranged the bolt slots 6 which extend for a short distance into the body of the block at right angles to the length of the tie. On the under-side adjacent each slot the block 2 is cut away at 7 forming an undercut recess. to receive the head of an anchor bolt, as will hereinafter more fully appear.

The concrete 8 fills the interior of the channel as well as incases it on all sides with a heavy layer, the said concrete formthe main body of the tie in which the channel 2 is thoroughly embedded. To further reinfoli'ce and hold together the concrete 8 a multi-apertured reinforcing member 9 is provided. This reinforcing member may consist of wire mesh, expanded metal, perforated sheet steel, or any structural element having analogous characteristics. In the drawings the reinforcing member 9 is illustrated as composed of wire mesh, or woven wire. thesaid mesh extending externally around the channel 1 embedded in thelayer of concrete in which the said channel is incased, and serving to reinforce said layer in a very substantial. way, as will be understood. by those skilled in the As will be. noted in the drawings, the anchor blocks 2 are of such thickness that their top surfaces are substantially flush with the top surface of the concrete while the lateral edges of said blocks in which the bolt slots 6 are arranged are substantially flush with the lateral concrete surfaces of the tie, the said top surface and lateral surfaces of the blocks 2 being thus exposed externally when the tie is completed, said surfaces being the only metal surfaces exposed in the tie proper.

The cushion blocks 10 may be constructed of wood, or other material or composition possessing resiliency. Each cushion block as the anchor blocks 2 and is providedwithbolt slots 11 adapted'to register with the corresponding slots 6 in the anchor blocks, said slots 11 being so arranged as to be disposed transversely with reference-to the length of. the tie.

anchor blocks connected thereto an'dthe reinforcing member 9'being arranged in the mold and the concrete added while in a plas tic state and allowed to harden in the usual wav.

- In use the ties proper should be laid upon-a suitable road bed with the anchor blocks turned upwardly. It will be noted that I have shown'the' tie aswider at the base than at the top. This not only makes the tie more stable when in position [and more properly distributes the downward pressure but also serves to anchor the tie to the roadbed when filling is arranged between the ties, as is a' common practicein well built railways. 'lVhen the'ties have been so arranged as above described, with the blocks 2 turned upwardly one'of the cushion blocks 10 is arranged upon' each of the anchor blocks 2 and the rails 3' are then placed upon the blocks 10. For' the purpose of covering and 1pg-otecting the exposed portions of'the bloc 10 and for fastening the rails to the ties the rail holding caps 12 are provided. Said caps are preferably formed of metal and two of such'caps are used at each cushion block. It .will be understood that the cushion blocks 10 are of such widthas to extend, longitudinally-of the tie, be

yond the lateral edgesof theraili base and the top 13 and depending flanges 14-. and 15 at the ends and one ofthe sides of the said top serve to cover and protect that portion of the block 10 which projects-beyond the rail base as described. F ormed integrally with the top 13, is also the 'rail engaging flange l6at the side of said top opposite the flange 15. Said flange 16 is' adapted to,overlie the base of the rail as illustrated in Figs.

- ,The anchor bolts 17 are slidably entered into the slots 6 and 11 with their heads, in the recesses at 7. The apertures 18 in the top 13'of the rail holding caps are'adapted to'permit said anchor bolts 'topas's therethrough and anut 19, with a jam nut 20' if desired, isemployed'toclamp the cap12 and block 10 to'theb'lock2. Such clamping action will bring the flanges lti of the two caps disposed on the opposite sides of the rail into clamping engagement with the base of said rail, thus holding said rail downtightly upon'the block 10;. It should be noted that when the parts are thus in position the caps 12 serve to maintain the bolts 17- passing through the slots 6 and 11 and apertures 18 in proper position, it being necessary not.

. I their position relative to the other parts. The ties proper should of coursebe molded in suitable forms the channels with the Special attention is directed to the fact that substantially no part of the metal mem bers of the tie proper are exposed to the somewhat protected from the action of the elements, and the lifeIof the tie proper is thus greatly prolonged. The blocks 10 may be renewed from time to time if necessary by loosening the nuts 19 and 20, removing the cap 12 and removing'the anchor bolts ,17, and the rails may be replaced or moved when desiredinla similar manner. In replacing ralls 1t 1s necessa to remove the capson one side only of t e length of the rail to bereplaced and then laterally moving the old rail to detach it and reversingthis operation for the fastening of the new rail.

The slots 6 and 11 are disposed transversely with "reference to the length of the tie, as hereinbefore stated. Any side movement of the rail'3 will be prevented by reason of the fact that the caps 12 are held tightly in place by the bolts 17 and said bolts" cannot move longitudinally of the tie by reason of the 'fact-that-they are held firmly in place by the sides of the said slots 6 and 11'. .The only direction lof'mo'vement of the bolts 17 by which the various parts may be loosened is a lateral movement with refer ence to the-length of the tie, following out through the slots 6 and 11.- Such lateral movement is preventedso long as the caps 12 l are in place upon said bolts, and therefore when the various parts are fully assembled and the bolts drawn upfirmly a very substantial andstrong fastening'is made.

caps 12' may be replaced-when necessary,

although such replacement, especially of the caps, will be rarely required. In replacing the blocks 10,'the ca'ps-12-*or thebolts l7 it is unnecessa'ry to disturbthe rail 3, as the .parts miay .be' slidablyI-remov ed-and new par'tsslidably' placed in position ,be clearly'underst'oodnecessary may bemade"'at slight expense.
